On the lattices of exact and weakly exact structures
We initiate in this article the study of weakly exact structures, a generalisation of Quillen
exact structures. We introduce weak counterparts of one-sided exact structures and show …

[HTML][HTML] Grothendieck groups of d-exangulated categories and a modified Caldero-Chapoton map
P Jørgensen, A Shah - Journal of Pure and Applied Algebra, 2024 - Elsevier
A strong connection between cluster algebras and representation theory was established by
the cluster category. Cluster characters, like the original Caldero-Chapoton map, are maps …
